Effects of training load indicators of recovery and injury occurrence in collegiate women volleyball players

Abstract

The purpose of this study was to determine the physical demands of a volleyball preseason training cycle using various types of training load and the relationship between training loads and injury. Twelve experienced female collegiate volleyball players (19.6 ? 1.2 years) participated in this project. The reactive strength index was used to estimate neuromuscular fatigue. The perceived recovery status scale was used to determine subjective recovery. External load measurements were acquired through the use of player monitoring units including accelerometers worn around chest. Injuries were evaluated and recorded by the athletic training staff. Significant correlations were found between sRPE load and mechanical load (r = 0.581), sRPE and total impacts (r = 0.640), total impacts and mechanical load (r = 0.914), sRPE load and injury (r = 0.753), mechanical load and injury (r = 0.689), and total impacts and injury (r = 0.671). No significant relationships were found between sRPE load or mechanical load with RSI or PRS. No significant relationships were found between injury occurrence and the sum of contacts in impact Zones 3, 4, 5, or the sum of Zones 4, and 5.
